General description
Terephthalic acid belongs to the class of monomers known as aromatic dicarboxylic acids. It is primarily used as a key monomer in the production of a high-performance polymer known as polyethylene terephthalate (PET). It is also used to prepare other polymers such as polybutylene terephthalate (PBT), polymer blends, and alloys. Terephthalic acid-based polymers are widely used in various industries including, packaging, textile fibers, polyester resins, polyurethane coatings, polyurethane foams, protective coatings, electrical components, and automotive applications due to their excellent properties such as high thermal stability, chemical resistance, lightweight, transparency, high strength, and durability. In the medical industry, terephthalic acid-based polymers may be used in the production of medical devices and equipment such as surgical sutures, tissue engineering scaffolds, and vascular grafts due to their biocompatibility, chemical resistance, and ease of processing.
